
When the data types of input variables are not BOOL, TIME, DATE, TOD or STRING, the input
parameters
In0~InN are allowed to connect the variables of different data types.

When the data types of input variables are one of BOOL, TIME, DATE, TOD and STRING, all the
input variables and output variable should be of the data type. For example, if the data type of
In0 is
TIME, the data types of the variables connected to In1~InN and Out must be TIME. Otherwise, an
error will occur during the compiling of the software.

Precautions for Correct Use

The input variables are not allowed to omit. An error will occur during the compiling of the software if
the input variables are omitted. But the output variable is allowed to omit.

The length of the data type of the output variable must contain the length of the variables that the
input parameters
In0 ~ InN connect. Otherwise, an error will occur during the compiling of the
software.

Programming Example

The data types of MUX_K, MUX_In0 and MUX_In1 are UINT, UINT and DINT and the data type of
Out1 is DINT. When MUX_EN is TRUE, the value of Out1 is 50 if the values of MUX_K, MUX_In0
and MUX_In1 are 0, 50 and 100 as shown in the following table Variable 1. If the values of MUX_K,
MUX_In0 and MUX_In1 are 1, 50 and 100, the value of Out1 is 100 as shown in the following table
Variable 2.

Variable 1

MUX_EN BOOL TRUE
MUX_K USINT 0
MUX_In0 UINT 50
MUX_In1 DINT 100
